Camille Pissarro painted "Red Roofs" using complementary colors like red, green, orange, and blue to create vibrant contrasts that enhance the visual impact of the scene. By placing these colors side by side, he achieved a dynamic interplay that reflects light and adds depth to the landscape. This technique also aligns with the Impressionist movement's emphasis on capturing the effects of light and atmosphere, allowing viewers to experience the warmth of the rural setting. Pissarro's use of color ultimately contributes to a sense of harmony and vitality within the composition.
